FTDI USB to Serial Converter Cable, DB9 RS232

A USB to RS232 converter in the classic format: a USB plug on one end, a serial interface on the other, driven by the FTDI chipset that most serial software expects. It is the dependable way to give a modern machine a real RS232 port, or to bring an old instrument, scale or controller back into service.

It is port-powered, so no external supply is needed, and it supports all the RS-232C signals — TX, RX, RTS, CTS, DTR, DSR, RI and GND — at rates from 300 baud to 460,800 baud. Data-direction auto-turnaround removes the need for flow control, and TX/RX LEDs show traffic at a glance.

Specifications

One thing to confirm: the item name says 0.35 m, while the feature list quotes a 6 ft (1.8 m) cable — the factory sheet carries both lengths. Tell us the length you need and we will supply the matching build. Everything else about the adapter is the same.

Typical applications

• Adding a serial port to a laptop without one
• Connecting scales, instruments and controllers over RS232
